> I recently had a house burn down in a neighborhood with numerous $150k houses. Cost to rebuild a similar structure was over $200k

My home insurance company made this very clear when I started a policy with them - they discussed the price of the house (e.g. in tax roll estimates of "land improvement") vs their estimated replacement cost. Even with new requirements though, no one talks about the productivity improvements in construction - from faster to put up materials, to the abundance of various tools .. is it really regulations or a form of cost disease...
